Overview of Market Risk
Market risk is the potential for changes in the market value of trading and investment positions
Primary exposures include interest rates, currencies, equities (and other asset prices), and commodities
![Page 4: Risks-in-IB](https://reader031.vdocuments.us/reader031/viewer/2022021402/55cf863e550346484b95a90b/html5/thumbnails/4.jpg)

Overview of Market Risk cont’d High sensitivity to the business
environments being operated in These depend on:
Global GDP growth Efficient capital markets Low inflation High business and investor confidence Geopolitical conditions Business earnings

Market risk effect on Investment Banking Market for M&A and underwriting is
limited by investor and CEO confidence in the economy
Clients are also highly dependent on liquid credit markets to finance major transactions
These large transactions are the major driver of Goldman’s M&A revenue
![Page 6: Risks-in-IB](https://reader031.vdocuments.us/reader031/viewer/2022021402/55cf863e550346484b95a90b/html5/thumbnails/6.jpg)

Market risk effect on Trading & Arbitrage Trading & Arbitrage opportunities
depend on market volatility A volatile market can therefore
increase trading revenues Conversely increased volatility
increases VaR as trading activity becomes more risky – this may force the firm to reduce trading activities to reduce VaR
![Page 7: Risks-in-IB](https://reader031.vdocuments.us/reader031/viewer/2022021402/55cf863e550346484b95a90b/html5/thumbnails/7.jpg)

Market Risk effect on Asset Management Asset Management fees are directly
based on the value of client’s portfolios
Uncertainty, volatility, adverse economic conditions and lower asset values can reduce these values and ultimately lower revenues
Risk of inability to attract new clients or hold onto existing clients

How Market Risk is Managed Diversify exposures Control Position Sizes Economic hedges in related
securities or derivatives E.g. hedging a portfolio of common
stocks by taking an offsetting position in an equity index

Tools for Managing Market Risk VaR; Value at Risk is a summary of
market risk exposure Sensitivity/scenario analyses, stress
tests, other analytical tools to measure effect of variables such as widening credit spreads, decline in equity markets, emerging market moves
Inventory position limits for selected business units

VaR
Potential loss in value of trading positions due to adverse market movements
A one-day time horizon is used with a 95% confidence interval
![Page 11: Risks-in-IB](https://reader031.vdocuments.us/reader031/viewer/2022021402/55cf863e550346484b95a90b/html5/thumbnails/11.jpg)
11
Benefits of VaR
Covers linear and nonlinear risk exposures
Responds to the change in the composition of trading portfolios
Estimates aggregate risk Reflects risk reduction due to
diversification
![Page 12: Risks-in-IB](https://reader031.vdocuments.us/reader031/viewer/2022021402/55cf863e550346484b95a90b/html5/thumbnails/12.jpg)
12
Weaknesses of VaR
Past changes do not necessarily reflect future performance
Trading gains/losses due to market movements may differ from the model
![Page 13: Risks-in-IB](https://reader031.vdocuments.us/reader031/viewer/2022021402/55cf863e550346484b95a90b/html5/thumbnails/13.jpg)

VaR
Components of Goldman’s VaR: Interest rate risk arises primarily from
exposure to changes in level, slope, and curvature of the yield curve; interest rate volatility, mortgage prepayment speeds, and credit spreads
Equity price risk arises from exposure to individual equity prices, baskets of equities, and equity indices
![Page 14: Risks-in-IB](https://reader031.vdocuments.us/reader031/viewer/2022021402/55cf863e550346484b95a90b/html5/thumbnails/14.jpg)

VaR
Components of Goldman’s VaR Currency rate risks arise from changes in
spot and forward prices and volatility of currency rates
Commodity price risk arises from changes in spot prices, forward prices, and volatilities of various commodities
![Page 15: Risks-in-IB](https://reader031.vdocuments.us/reader031/viewer/2022021402/55cf863e550346484b95a90b/html5/thumbnails/15.jpg)

Average Daily VaR at year-end
VaR increased from 180 to 218 from 08 to 09. Due to increase in interest rates category (widening spreads) and reduction in diversification benefit across risk categories.
![Page 16: Risks-in-IB](https://reader031.vdocuments.us/reader031/viewer/2022021402/55cf863e550346484b95a90b/html5/thumbnails/16.jpg)

17
Year-end Daily VaR
VaR as of December 2009 decreased due to a large reduction in interest rate category and a reduction in currency rates category (lower volatility in FX markets), offset partially by an increase in equity prices category (due to higher levels of exposure).

Daily trading revenues are compared with prior day VaR for risk management purposes. In 2009, daily trading losses did not exceed VaR on any day.
![Page 20: Risks-in-IB](https://reader031.vdocuments.us/reader031/viewer/2022021402/55cf863e550346484b95a90b/html5/thumbnails/20.jpg)

Analysis of VaR The interest rates category is by far
the largest component, at 44% and 68% of pre-diversification effect VaR in 2009 and 2008 respectively

Daily VaR during 2009
VaR at year-end was lower than in the previous year but average daily VaR was much higher in 09 than in 08 VaR – was very high in the first to quarters of 2009
![Page 25: Risks-in-IB](https://reader031.vdocuments.us/reader031/viewer/2022021402/55cf863e550346484b95a90b/html5/thumbnails/25.jpg)

Daily VaR since Q4 2009
![Page 26: Risks-in-IB](https://reader031.vdocuments.us/reader031/viewer/2022021402/55cf863e550346484b95a90b/html5/thumbnails/26.jpg)
26
Other Market Risk Measures VaR does not include the impact of
changes in the credit spreads of derivative counter-parties or Goldman’s own credit spreads
A one basis point increase in these credit spreads would produce a $1M loss of net revenue and a one basis point decrease would produce an $8M gain for net revenue
![Page 27: Risks-in-IB](https://reader031.vdocuments.us/reader031/viewer/2022021402/55cf863e550346484b95a90b/html5/thumbnails/27.jpg)
27
Other Market Risk Measures For inventory positions not included
in VaR, sensitivity analysis is used, Goldman analyzes the effect on net revenues of a 10% decline in the underlying value of the positions
![Page 28: Risks-in-IB](https://reader031.vdocuments.us/reader031/viewer/2022021402/55cf863e550346484b95a90b/html5/thumbnails/28.jpg)

What is credit risk
The loss that GS would incur if Counterparty in a security of other
financial instrument defaults on GS Value of securities GS holds decrease
due to decrease in credit quality / ratings▪ Securities include OTC derivatives
![Page 31: Risks-in-IB](https://reader031.vdocuments.us/reader031/viewer/2022021402/55cf863e550346484b95a90b/html5/thumbnails/31.jpg)
31
Sources of Credit Risk
Arises from running its core businesses Trading
▪ OTC Derivatives, Counterparties in trades, etc Investing (Principal investments)
▪ Issues faced by all Hedge funds & PE firms▪ Investments defaulting, portfolio companies’ client
defaulting, etc Financing Activities
▪ Used to win investment banking mandates, as competitors (JPM, BoA ML, Citi, etc) all have huge balance sheets to be used to win mandates.

32
Managing Credit Risks
A significant amount of GS’ credit is concentrated within the financial services industry Significant amount of counterparties are
firms within the same industry Netting agreements with counterparties
in regards to payables and receivables Similar to how in interest rate swaps work Only the net amount between A/R and A/P
changes hand

33
Managing Credit Risks (2) For select clients / firms:
Obtain upfront or contingent collaterals Have 3rd party as guarantor for the
counterparties’ obligations Transfer credit risk through hedging with
available derivatives▪ If no direct hedges are available, structure a new
derivatives contract to hedge the risk There is no credit exposure bigger than
2% of the firm’s balance sheet other than US government securities
![Page 34: Risks-in-IB](https://reader031.vdocuments.us/reader031/viewer/2022021402/55cf863e550346484b95a90b/html5/thumbnails/34.jpg)

Measures of Credit Risks
Potential Exposure to credit risks Estimate credit exposure within a given
confidence level, during the life of the transaction and market movements
Changes in Credit Spread VAR
Scenario Analysis To supplement the other measures Credit Spread widening scenarios Stress tests

Operational Risk Factors
Risk of loss due to internal failures Operational risk also stands to cause
reputational harm Managed through continual
development of control standards

39
Operational Risk Factors
Investment banks have a legal separation between their investment banking and sales & trading businesses – known as a Chinese Firewall
This presents a risk of operational failure and reputational harm when information is leaked between these two lines of business
